If I build efficacy in one domain, does it spill over to other domains?

Partially. Bandura: efficacy is domain-specific but partial "generalization" is possible. Higher efficacy in exercise → more willingness to try new challenges. But not automatic — each domain needs separate build-up. The "pattern (failure → learning → success)" of small successes does generalize.

It's hard to find "appropriate models" in Korea.

Korean media show only "successful people", giving many unrealistic models. Alternatives: 1) people in "similar circumstances" in self-help groups / online communities (DC, cafés), 2) "mid-success" figures in books / documentaries, 3) family / colleagues "one step ahead" of you, 4) your own self 1–5 years ago (use yourself as a model).

My efficacy is near zero — where to start?

Severe depression / CPTSD may be comorbid — start with psychiatry / psychotherapy. But small starts: 1) acknowledge the smallest daily successes (brushing teeth, making the bed), 2) record one "thing I did today" daily, 3) 5-min walk for 1 week, 4) meet a friend slightly ahead of you weekly. Efficacy build-up takes time (6 months – 2 years).

Self-efficacy — Albert Bandura's "I can do this", a core predictor for depression / anxiety / addiction / chronic pain, the 4 sources of efficacy information

Albert Bandura's (Stanford, 1977) Self-Efficacy theory: "the belief that you can produce the desired outcome in a specific situation". Not simple "confidence" — a belief about specific domains / tasks. 50 years of research established it as a core predictor across nearly all clinical domains: depression, anxiety, addiction, chronic pain, academics, exercise, smoking cessation, weight. 4 sources of efficacy information: ① mastery experience (direct experience — most powerful), ② vicarious experience (similar others), ③ verbal persuasion ("you can do it"), ④ physiological / emotional states (interpreting heart rate / tension). Korea's "my fault / I'm inadequate" culture (#261 learned helplessness) lowers efficacy and raises depression. 5-step efficacy improvement: small successes, find models, coach, body regulation, reinterpretation.

1. Bandura 1977 — the discovery of "self-efficacy"

Albert Bandura (Stanford, 1925–2021) published "Self-Efficacy: Toward a Unifying Theory of Behavioral Change" in Psychological Review in 1977. Core proposition: the determining variable of behavioral change is not "skill / motivation / environment" but "the belief that I can do it" (self-efficacy). Two people with the same skill and environment can have different outcomes due to a "belief" difference.

2. Self-efficacy ≠ confidence

Dimension	Self-efficacy	General confidence
Target	Specific tasks / domains	General self
Example	"I can score 80 on this test"	"I'm a confident person"
Measurement	Task-specific score (0–100%)	General scale
Changeability	High (interventions possible)	Low
Predictive power	Very strong	Weak

Not "I am confident" — measure / intervene per domain.

3. Clinical effects — across nearly all domains

Domain	High-efficacy group outcome
Depression recovery	Better treatment response, less relapse
Anxiety (phobia / PTSD)	Better exposure-therapy effect
Smoking cessation	×2.5 abstinence at 1 year
Alcohol / addiction recovery	Less relapse
Chronic pain (#241)	More activity, lower pain reports
Diabetes / CVD self-management	HbA1c, BP ↓
Exercise maintenance	×2 maintenance at 6+ months
Weight-loss maintenance	Less yo-yo
Academic performance	Higher achievement, less dropout

4. 4 sources of efficacy information (Bandura)

1. Mastery Experience — the most powerful

Direct experience of success. Accumulated small successes raise efficacy. Even overcoming failure with "effort + strategy + perseverance" builds stronger efficacy.

2. Vicarious Experience

Observing success in "people like me". "If they did it, so can I". Maximum effect when the model is not a "distant hero" but "someone with similar conditions who succeeded with effort".

3. Verbal Persuasion

External encouragement like "you can do it". Effective but weaker than direct or vicarious. "Evidence-based encouragement" (pointing to specific strengths) > "empty praise" ("you'll do well").

4. Physiological / emotional state

How you interpret heart rate ↑, muscle tension, sweat. Reinterpreting from "tension = threat" to "tension = preparation" raises efficacy. Crum 2013 Yale: groups who saw the same body signal as "arousal" rather than "tension" scored higher.

5. The cost of Korea's "I'm inadequate" culture

Comparison culture (#260) turns "models" into "mom's-friend's-kids / geniuses" — no vicarious experience ("I'm different from them")
Perfectionism (#218) → small mistakes are "failures" — no mastery experience forms
"No-praise" parents / teachers → no verbal persuasion
"I am tense" → "tension = inadequacy" interpretation → efficacy ↓

6. 5-step efficacy-building protocol

Step 1: identify and measure the domain

In which domain is your efficacy low? (work, relationships, exercise, smoking cessation, etc.)
Self-rate 0–100%
Below 40% → needs active intervention

Step 2: accumulate small successes (Mastery)

Break the big goal into 10 steps
Start with the smallest step
Record and acknowledge each success
On failure, revise the strategy — not "insufficient effort"

Step 3: find similar models (Vicarious)

Find people with similar starting points who succeeded
Friends, family, self-help groups, online communities
Not "distant heroes" — "nearby models"
Weekly dialogue or content exposure with a model

Step 4: secure a coach (Verbal Persuasion)

1–2 people who concretely recognize your strengths
Not empty "you'll do well" — "you achieved ~ before, so this is also possible"
Therapist, coach, mentor

Step 5: body / emotion reinterpretation

"Tension = threat" → "tension = preparation"
Calm with deep breathing (#272)
"I think I'll fail" → "tension is natural"
Raise baseline through exercise, sleep, diet

7. School / workplace application

How teachers / managers raise students / subordinates' efficacy

Set challenges at "appropriate" difficulty (Flow #269 challenge-skill balance)
Concrete, process-focused feedback (growth mindset #257)
Expose them to similar peer models ("your peer ~ did ~")
Disclose your own failures (vulnerability #264)
Autonomy support (#266 SDT)

8. Building children's efficacy

Praise "effort" not "smartness" (#257)
Opportunities for achievement (small responsibilities / decisions)
Reframe mistakes as "learning material"
Show your own challenges and effort
Don't burden them with "you know everything / you're perfect"

9. Korean resources

"Self-Efficacy" (Bandura, Korean edition)
Korean Psychological Association cognition / motivation division
CBT-integrated efficacy work (psychiatry / clinical psychology)
Coaching certification bodies (KPC, ICF Korea)
Outside therapy — self-administration: journaling, habit-tracking apps

10. Efficacy vs "false confidence"

Efficacy ≠ grandiosity / unfounded confidence. Bandura emphasized that efficacy is grounded in "empirical information". Weak sources 1 / 2 risk "unfounded efficacy" — bigger frustration on failure. "Building up" efficacy with small successes is core.
